Question

if a and b are relatively prime numbers then what is their HCF and LCM

Answer 1

LCM is a ×b

aur HCF of a into b of common numbers of greater power

Answer 2

numbers are said relatively prime or co-prime if they dont have any common divisor.

E.g consider 13 and 14

Factors of 13 are 1 and 13

Factors of 14 are 1, 2, 7 and 14.

Here, only common factor is 1.

Hence 13 and 14 are relatively prime numbers.

And HCF of relatively prime numbers is always 1.
